Recurrent otitis externa in dogs: cytology and rechecks

Recognize the range of presentations

Otitis externa can present in many ways, from head shaking or discharge alone to obvious ear pain with head tilting. [1]

Acute and chronic otitis externa should be approached differently, because the organisms involved usually differ. [1]

Let cytology guide product choice

Long-acting in-clinic otic products are meant for acute otitis externa, which typically involves cocci such as staphylococci. When cytology shows rods, they are unlikely to work and are best avoided unless there is no other option. [1]

Recheck before calling it resolved

A recheck matters because debris deep in the canal can persist even when the ear looks clinically improved, and the problem is not resolved until it is gone. [1]

Frank blood in the ear canal should raise suspicion of a mass. [1]
